This wire should be as short as possible and any paint or rust at the grounding point should be scraped away to provide a clean metal surface to which the end of the ground wire can be screwed or bolted. 3. Remote Turn-On Connection The amplifier is turned on by applying +12 volts to the remote turn-on terminal (REM). The wire lead to this terminal should be connected to the "Auto-Antenna" lead from the car stereo which will provide the +12 volts only when the car stereo is turned on. If the car stereo does not provide an Auto-Antenna lead, the remote turn-on lead may be wired to an "Accessory" or "Radio" terminal in the car's fuse block. This will turn the amplifier on and off with the ignition key, regardless of whether the car stereo is on or off. The remote turn-on lead does not carry large currents, so #20 gauge wire may be used for this application. -4 WIRING INSTRUCTIONS 4. Speaker Connections Wire the speakers to the "Speaker Output" terminals as per the Output Wiring Diagram (remove 1/4" of insulation from the end of each wire, depress the spring tab on the connector, insert the wire and release the spring tab). For most applications, #18 gauge wire should be used for the speaker leads but in no case thinner than #20 gauge. When wiring the speakers, pay careful attention to the polarity of the terminals on the speakers and make certain they correspond to the polarity of the corresponding terminals on the amplifier. DO NOT ground any speaker leads to the chassis of the vehicle. 5. Input Connections This amplifier features both high and low-level input capability. Use either the low-level or high-level inputs, not both. If low-level outputs are provided from the car stereo, it is recommended that the low-level inputs be used for lowest distortion and best performance. Use good quality shielded audio cables with RCA plugs at both ends to connect the stereo to the amplifier and keep the cable lengths to a minimum to avoid noise. If the car stereo does not provide low-level outputs, the amplifier may be connected via the speaker (high-level) outputs from the stereo. Wire the positive (+) speaker leads from the car stereo to the 5-pin adaptor harness as shown in the diagram (shielded cable is not required for this application) and plug the connector into the mating High-Level Input socket on the amplifier. Carefully splice and insulate all wire connections. CAUTION: Use either the low-level or the high-level inputs on the amplifier. DO NOT use both input levels at the same time. -5 PWR HIGH LEVEL LOW INPUT GAIN MIN MAX MIN MAX GAIN INPUT WIRING DIAGRAM -6- 5-PIN CONNECTOR IMPORTANT USE EITHER HIGH-LEVEL OR LOW-LEVEL INPUTS, NOT BOTH.

If, however, there is still output from the amplifier when the car stereo volume control is at its minimum setting, or the output level increases too fast with a small rotation of the volume control, adjust the Level control to decrease the output from the system. Once the correct setting is found, these controls should not require any further adjustment. 3 Fuse The circuitry of the amplifier is protected from damage by an automotive-type fast-blow fuse. If fuse replacement is necessary, use only fuses of the same ampere rating as originally supplied with the unit. The use of fuses with incorrect ratings may cause serious damage to the amplifier. If fuses blow consistently, carefully check all electrical connections to the unit.
